"Grand Theft Auto is a cultural phenomenon and Rockstar Games continues to redefine what can be achieved in interactive entertainment," said Strauss Zelnick, chairman and CEO of Take-Two, in a statement touting the milestone. "We are incredibly proud of the extraordinary critical and commercial response to Grand Theft Auto V."

The figure outpaces Activision Blizzard's Call of Duty II: Black Ops, which took 15 days to hit that milestone after its release last November.

Both Activision Blizzard and Take-Two Entertainment compared their respective title launches to the $1.5 billion global box-office haul by Marvel's The Avengers in 2012.

GTA V previously claimed the record for single-day sales, raking in $800 million upon release Tuesday. Call of Duty, the prior record-holder, had nabbed $500 million in first-day global sales upon release.
